A solar cell substrate with thin film polysilicon. The solar cell substrate includes a substrate; a transparent conductive layer, formed on the substrate; a thermal isolation layer having inlaid conductive layers, formed on the transparent conductive layer; and a polysilicon layer, formed on the thermal isolation layer.

Solar cell substrate with thin film polysilicon

This invention discloses a novel method for fabricating solar cells. Using the existing screen-printing, masking or photolithography techniques, a P-type or N-type diffusion source is coated on the sites of an N-type or P-type silicon wafer desired for forming electrodes. Then, a low dose P-type or N-type diffusion source is in situ diffused into the N-type or P-type silicon wafer together with the P-type or N-type diffusion source coated on the N-type or P-type silicon wafer in the furnace. Thereafter, a P,/P,or N,/N,diffusion region is formed within the N-type or P-type silicon wafer. Finally, electrodes aligned to the P,or N,diffusion region are formed by means of screen-printing. Then, a solar cell with high photocurrent and low series resistance can be obtained.
